Battery material, promote renewable energy development

In recent years, with the increasingly serious problems of environmental pollution and energy shortage, renewable energy as a clean, low -carbon, and sustainable development model has gradually been given important strategic significance. Among the applications of renewable energy, batteries as energy storage equipment are also an indispensable part of them. In order to further promote the development of renewable energy, we need to continuously explore new battery materials to improve the power density, cycle life and security of the battery.At present, researchers have proposed many new battery materials, such as lithium ion batteries, sodium ion batteries, zinc air batteries, etc. These battery materials can better meet the needs of energy storage and utilization compared to traditional lead -acid batteries, nickel -metal hydride batteries. Moreover, in the production process, the energy and materials they consume are also greatly reduced, which is more in line with the requirement

Graphite products conductive material

Graphite is widely used in the electrical industry for electrodes, brushes, carbon rods, carbon pipes, mercury tubes, cashiers, cashmerers, telephone parts, televisions, coatings of televisions, and so on. Among them, the application of graphite electrodes is the most widely used. When smelting various alloy steel and iron alloy, use graphite electrodes. At this time, the powerful current passes through the melting area of the electric furnace to generate an arc, which translates the electric energy to the heat energy, and the temperature is increased to the left and right. So as to achieve the purpose of melting or reaction. In addition, when electrolytic metal magnesium, aluminum, and sodium, the anode of the electrolytic groove also uses graphite electrodes. The resistance furnace that produces rigid sand was also used as a furnace head conductive material with graphite electrode. The graphite used in the electrical industry is high in granularity and taste. For example, alkaline b

The main production process of graphite electrodes

(1) Calcination. Both petroleum coke and asphalt coke need to be calcined at a temperature of 1350 ℃ to fully remove the volatile matter contained in the carbonaceous raw material and improve the true density, mechanical strength, and conductivity of the coke.(2) Crushing, screening, and batching. Crush and screen the calcined carbon raw materials into designated size aggregate particles, grind some coke into fine powder, weigh according to the formula, and aggregate to form a dry mixture of various particles.(3) Mix and knead. Mix and knead the dry mixture of various particles with a certain amount of binder in a heating state to form a plastic paste.(4) Forming. Under external pressure (extrusion molding) or high-frequency vibration (vibration molding), the paste is pressed into a certain shape and high density of raw electrodes.(5) Roasting. Place the raw electrode in a specially designed roasting furnace, and use metallurgical coke powder to fill and cover the raw electrode. At a

How to solve the corrosion of the device in the scale graphite?

How to avoid the corrosion of the equipment on the equipment, thereby reducing equipment investment and maintenance costs, and improving production efficiency and profits is a problem that each chemical enterprise always needs to solve. Many products are resistant to corrosion but not high temperature, but scales graphite has both advantages.

The key features of graphite

1. High fever and conduction: In response to the use of raw materials such as graphite with high thermal conductivity, it reduces the time of fusion.2. High temperature resistance: high -temperature resistance has strong impact characteristics, for rapid cold and hot heat, not easy to crack.3. High temperature resistance: high fire resistance, high temperature to 1200 to 1600 ° C.4. Anti -corrosion resistance: strong adhesion to resist melting soup.5.
